Eventually I stumbled upon this Feature, which is only working on these Samsung Devices: Galaxy S4, Note2 & Note3.
So I wondered if it got ported to any other Android Device yet, or if i can get this on my rooted HTC One.
video for the Application on Samsung Devices:

Summary: How can i get the swipe-feature from the Video on other Devices than Samsung, and if possible with the Latin IME from 4.4 KitKat?
